Raspberry Pi Pico 2 W

Raspberry Pi Pico 2 W board record: RP2350 with Wi-Fi and Bluetooth via the on-board CYW43439 radio, 4 MB flash, the same 40-pin J1/J2 layout as the Pico W, LED on the radio chip instead of GP25, and every published field with its fixed official source.

Revisions

v1 (the documented board) — The datasheet's release-history section tracks DOCUMENT releases, not PCB revisions; no per-revision board change table is published. The id 'v1' is a schema-required placeholder meaning 'the board as documented' — it is not a silkscreen revision claim. · Raspberry Pi Pico 2 W Datasheet (RP-008304) · pico2-w-ds.pdf#document-release-history

J1 (left header, physical pins 1-20) (20 pins)

Pin table reused from the verified Raspberry Pi Pico record: the official docs state the wireless boards share one pinout and board layout, and the SDK board header pico2_w.h sets identical UART/I2C/SPI defaults. Physical pins, silkscreen names and power/ground positions are therefore the same 40 positions as the Pico. Board-level differences from the Pico/Pico 2 are carried as claims on this record (LED wiring, GP23/24/29 radio use, SWD position), not as pin-table edits. · Source: Raspberry Pi documentation: Pico-series boards (pinout figures, board differences, SWD connector) · documentation/asciidoc/microcontrollers/pico-series/about_pico.adoc#layout_wireless

The Raspberry Pi Pico 2 W is the wireless RP2350 board: an Infineon CYW43439 radio chip on board (Wi-Fi 802.11n 2.4 GHz, Bluetooth 5.2) wired to the MCU over SPI, 4 MB of flash, micro-USB B, and the same 40-pin footprint and pinout as the Pico W — the official documentation states the wireless boards share one layout and pinout. This page renders the MCUID data record and every published field tied to a fixed official source.

Start developing

Bring-up — the Pico 2 getting-started guide covers the RP2350 flow; the W board follows it with board-specific firmware.
Chip capabilities and limits — the RP2350 chip page separates what the chip provides from what this board wires up, including the M33/RISC-V architecture switching.

Also known as: pico 2 w, pico2w, raspberry pi pico 2 w, rpi pico 2 w

Same as the Pico W — except the chip and flash

The layout, radio, internal GPIO wiring and SWD position are identical to the Pico W (the official docs describe all four wireless variants together). What changes:

RP2350 instead of RP2040 — dual-core Arm Cortex-M33 or dual-core Hazard3 RISC-V (selectable), 150 MHz, 520 kB SRAM; see the RP2350 chip page for what that switch means.
4 MB flash instead of 2 MB (SDK board header PICO_FLASH_SIZE_BYTES).

The wireless-circuitry notes on the Pico W page apply here one-for-one: LED on the radio chip (WL_GPIO0), GP23/24/25/29 consumed by the radio (GP25 = wireless SPI chip select, GP29 = SPI clock shared with the VSYS monitor), SWD pads centrally below the MCU (left to right: SWCLK, GND, SWDIO).

Flashing: BOOTSEL, volume RP2350 — and the right firmware

Hold BOOTSEL while plugging in USB; the board enumerates as a mass-storage volume named RP2350 — the same volume name as the non-wireless Pico 2, so the volume name alone does NOT tell W from non-W. Check the board itself (see the identification guide). Firmware targets differ three ways: pico2_w ≠ pico2 ≠ pico_w.

Wireless: capability and licence

Identical to the Pico W: CYW43439, Wi-Fi 802.11n 2.4 GHz (WPA3, soft-AP up to four clients), Bluetooth 5.2 (BLE Central/Peripheral + Classic); libcyw43/BTstack free for commercial use on wireless Pico boards per Raspberry Pi's granted licence.

The Raspberry Pi Pico W is the RP2040 generation of this board: same layout and radio, 2 MB flash, volume name RPI-RP2.
The Raspberry Pi Pico 2 is the non-wireless sibling: LED on GP25, SWD at the bottom edge, same 4 MB flash.
